X-600M Users Manual Appendix H: Custom Web Pages
1: {if $user->hasAccess(255)}
2: {$io->load()}
3: <html>
4: <head><title>Example</title></head>
5: <body><p>{$io->desc("owSensor1")}<p></body>
6: </html>
7: {/if}
Line 1: Checks to see if the user that is logged in can access this web page. It does this by calling the
hasAccess() function of the $user object. The hasAccess function takes as a parameter an access
mask. Each bit in this mask represents one of the User Access groups.
Bit Access Group Decimal Representation
1 admin 1
2 user 2
3 group1 4
4 group2 8
5 cbw 16
The way this works is that if the currently logged-in user belongs to at least one of the Access Groups
specified in the access mask (in this example 255, or any group), that user will be able to view the page.
Line 1: To create a page that only should be visible to the admin, you would use this for line 1:
{if $user->hasAccess(1)}
To create a page that should only be visible by the user access group, you would use this for line 1:
{if $user->hasAccess(2)}
Line 2: Will cause the template engine to load information about all the registered I/O on the X-600M.
The load function must be called for each object that is to be later used in the template.
Lines 3 and 4: Basic HTML.
Line 5: Contains the {tag} that will insert the description of a 1-Wire temperature sensor into the web
page. There are a few different values that we might be interested in seeing on the web page for this
sensor such as the units and the description. In this example we are only interested in the description.
To get the description of the 1-Wire temperature sensor, we call the desc function on the $io object and
pass it the name of the I/O we are interested in. In this case we are interested in the I/O with the name
“owSensor1”, hence {$io->desc(“owSensor1”)}
The following table lists all the objects and each of its functions/properties.
Note: Functions end with () and generally require a parameter. They are used to access the property of
an io, reg, etc by that io's name. Properties do not end with (), and can only be used inside foreach
loops.
Object Function Property Description
$io load() n/a Load I/O information from
settings.
desc(“ioName”) desc Get the description of the I/O
named ioName
units(“ioName”) units Get the units of the I/O named
